TUFTlN G-BUTTON FOR CUSHION-SEATS.

SPECIFICATION forming part of Letters Patent No. 630,553, dated August 8, 1899.

Application filed December 4, 1897. Serial No. 660,756. (No model.)

To all whom it may concern:

Be it known that I, FRED A. NEIDER, aeitizen of the United States, anda resident of Augusta, in the county of Bracken and State of Kentucky, have invented certain new and useful Improvements in Tufting-Buttons for Cushion-Seats, of which the following is a specification.

My -i nvention is an improvement in tuftingbuttons for cushion-seats, and particularly in the button-back, with its clenching-prongs formed integral therewith; In buttons of this kind heretofore used the tines or clenching-' use the prongs had a tendency either to straighten out or break off at an angle-bend near the body of the button.

The object of my invention is to ove this defect and form the tines or "clenchingprongs with a heavybase back of the buttong disk and taper this base down to a point some distance from the back of the button 'to its junction with the straight or parallel sides of the tines, so that in bending the inclination to bend is at the base of the tapered base, forming practically a neck for the button between the button-baek and the angular bend of the tines when turned over the bottom or base of thecushion-seat, whereby the strain upon the button and the tines .is a direct strain,havin g no tendency to breakthe clenching-prongs near the base of the button nor to straighten them out beneath the cushion-base. The invention will be fully understood from the following description of the accompanying drawings, in which- 7 Figure 1 is an inverted perspective view of a tufting-button embodying my invention. Fig. 2 is a central vertical sectional view of the same through line a: 00 of Fig. 1. Fig. 3

is a perspective view of the button, showing one of the clenching-prongs bent at an angle to the tapering base. Fig. 4 is an inverted plan view of the button-back as it comes from the stamping-machine and before the clenching-prongs are turned at right angle to it, as

shown in the preceding figures. Fig. 5 is a detail view in central vertical section of the cushion with my button applied to form the tufts.

The cap A is secured to the body of my improved back 13 in'the usual manner by having its edges flanged or turned over the edge of the back. The back 13, with its clenchingprongs I), having the flaring-base b tapering from its junction with the body to the point 19 is stamped out in the usual manner, with the single exception of the base b flaring from the point b to the points 19 which sever it from the body of the base and determines the line at which it is bent at a right angle to the base to pass through perforations in the foundation or base 0 of the seat.

The'tufting-button is applied in the usual manner, as illustrated in Fig. 5that is, the filling D is first placed upon the base, the covering material E turned over and secured to it and perforated opposite the perforations injthe foundation to receive the clenchingishanks b of the tufting-buttons, which are passed through the material, through the perforations in the base, pressed down to the position shown inFig. 5, and clenched over un- I As the prongs b are bent over the base they naturally bend at the point 12 flat upon the bottom of the base, leaving necks or straight portions between their angular bends and the bottom of the button, so that in use there is no tendency to straighten out the bends, as the line of the bend is clearly defined and at a right angle to the base. By this means a'cushion is left between the covering goods between the bottom of the button and the base, which prevents all tendency of the prongs to break either at their juncture with the body or at the point b ,where they bend around the'base of the cushion.

I have shown my clenching-prongs having a plain taper from the base to the point where it joins the parallel portions 1) of the clenchin g-pron gs, but it wouldbe an inferior modifieation of my invention to form the base with a square or rounded shoulder to define the line at which the prongs should bend when inserted for use, and I have also shown the common metallic flanged cap covering the back; but it is obvious to those skilled in the art that my back and clenching-pron gs may be used with any of the well-known forms of caps or top coverings, and while I have shown my invention in the best form which is known to me I do not desire to be limited to the specific details shown and described.

What I claim as my invention is 1. The button-back having formed integrally with it clenching-prongs adapted to be
